A new saving- in the turpentine industry [Forestry and Irrig., I ; i 190( 

 ■■'■, pp.99, 100). — Further economy has been effected by the Fores! Service in the 

 turpentine industry as the result of experiments carried oul during the past 

 which indicate that at least an equal How of resin can be secured from shallower and 

 shorter " faces." It is believed thai with this diminution in the severity of the facing 

 operation the ordinary term of 3 or 4 years during which a foresl is now worked can 

 be greatly increased.

Results of a Rocky Mountain forest fire studied fifty years after its occur- 

 rence, W. J. Gardner (Proc. Soc. Amer. Foresters, 1 i 1905), No. ?,pp. 102-109). A 

 report on an examination of the condition of the forests on the southern portion of 

 the Pikes Peak Reserve to determine to whal extent the denuded slopes of this 

 watershed are naturally reforested. 



The region comprises nearly 7'» square miles of extremely rugged mountain land. 

 More than 56 per cent of the district is above 9,000 ft. Three and one-half square 

 miles lie above the timber line. The prevailing forest type- are Engelmann spruce, 

 limber pine, red fir, and bull pine. Early in the investigation evidence was obtained 

 to show that a portion of the region had been severely burned about 50 years previ- 

 ously. The reproduction of the forests since that time has been slow and irregular. 

 In some places the new growth is exceedingly dense and in other- the ground is -till 

 perfectly bare. 



Relative to the aspen as a nurse-tree, it was observed that Engelmann spruce, red 

 tir, and other species came in after the fire quite regardless of aspen, though it is 

 stated that wherever the aspen does occur it undoubtedly acts as a valuable soil pro- 

 tector. Where the new growth occurs, Engelmann spruce is most abundant; three- 

 fourths of the young trees of this species was found to be M0 to 7)1) years old. but 

 comparatively little young growth has started within t he past 30 years. The spruces 

 grow extremely slow, trees L* to 4 ft. tall and 40 to 4"> years old being quite common. 

 On an average it is estimated that it takes an Engelmann spruce 25 to 35 years to reach 



a height ot 7) ft. in that region. Most of the diameters are helow 2 in. It is stated 



that the tolerance of Engelmann spruce is remarkable, as trees in old crowded pole 

 forests sometimes persist for 200 to 250 years without attaining a height exceeding 10 

 to L5ft. 



Investigations on the influence of forests on the ground water table,

 were studied. The more important conclusions are Btated as follows: 



The storing of the ground water is dependent first of all upon the seasonal distri-
